Ask the expert to teach the novice how to adjust the lens sensitivity, focal length and aperture when shooting food advertisements with Canon D550 indoors with windows.

1. Choice of lens: Macro lens is essential if you want to show the details of dishes. You can choose a 50mm or 60mm lens on the desktop, and the price is around 2000. If there is no macro lens, then 18-55 can make do.

2. Choice of light: It is recommended to light it yourself. The cheap solution is to take out the desk lamp at home (it is best to use three-color lamps, so the color temperature will be around 5500k, which is easy to adjust), and put several combinations according to the different colors of the dishes, and the observation effect is the best.

3. White balance, white balance in product photography is very important. Simply put, white is white and black is black, because the reflection of light by objects may cause inaccurate color temperature. All white papers define white balance in advance.

4. Exposure, you have to accurately measure and expose which part of the dish you want to show.

5. Creativity, the arrangement of dishes and the addition of other personality elements will add a lot of color to the photos.

6. After that, make post-adjustment according to the situation to improve contrast, sharpening and saturation.
